is the bathroom on a different floor or something, throwing feces out a window sounds like very strange behavior, seems like it would also create an unsanitary/health hazard in the room as well. I would get her out of there fast as you can,, I was reading about "boarder" rights just last week,, if your only renting out a room she is not a tenant but a boarder, and they have less rights depending on your state, but the info I was reading suggested that if a boarder pays by the week, you can give her notice and she needs to clear out in 7 days, if she pays by the month it would be 30 days, I would look into the boarder laws for your state, google "boarder rights -your state" and see if that same process applies to your case. good luck with this.
